Niobium tungsten oxides for high-rate lithium-ion energy storage

Niobium tungsten oxides for high-rate lithium-ion energy storage, Published online: 25 July 2018; doi:10.1038/s41586-018-0347-0

Micrometre-sized particles of two niobium tungsten oxides have high volumetric capacities and rate performances, enabled by very high lithium-ion diffusion coefficients.

Wave energy converters are not geared towards the increase in energy over the last century

Wave energy converters are designed to generate the maximum energy possible in their location and take a typical year in the location as a reference. Researchers have been exploring how ocean energy in Ireland has evolved during the last century. The results reveal an increase of up to 40%, which directly affects the output of the converters.

Bacteria-powered solar cell converts light to energy, even under overcast skies

Researchers have found a cheap, sustainable way to build a solar cell using bacteria that convert light to energy. Their cell generated a current stronger than any previously recorded from such a device, and worked as efficiently in dim light as in bright light. This innovation could be a step toward wider adoption of solar power in places like British Columbia and parts of northern Europe where overcast skies are common.
